Vacuum Insulation Performance
Built for outdoor work and long-distance travel scenarios, this thermos addresses the practical pain points of inconvenient water refills and insufficient insulation time during long outings. The double-wall vacuum structure reduces heat transfer to maintain temperatures for 6 to 12 hours. It works for hot drinks in winter and iced beverages in summer, supporting use across all seasons for people who spend extended periods outside.
Rugged Build for Harsh Environments
The thickened stainless steel body resists impact and compression, and holds up to bumps and knocks in demanding outdoor settings such as construction sites and hiking trails. The screw-on sealing lid has a durable design that withstands frequent repeated opening and closing with minimal wear, supporting long service life under high-frequency, heavy-use conditions. A MARSCOAT easy-clean coating on the interior simplifies removal of daily drink residue.
On-the-Go Usability
The body diameter fits most car cup holders and backpack side pockets for easy access and storage. The 500ml capacity provides enough stored water for full-day outdoor work, travel or field activities without frequent stops to refill. The 304 food-grade stainless steel inner liner meets all food contact safety requirements.
